A nationwide crackdown on unsafe bus companies has shut down 52 companies nationwide including two in Arizona.
According to an Associated Press interview with the administrator of the Federal Motor Carrier Safety Administration, two recent bus accidents including one near Los Angeles where several people were killed served as an eye opener for the department.
The agency started investigating 250 bus companies plagued with safety issues.
The violations it found ranged from maintenance issues and tired drivers driving more than 800 miles to drivers with suspended licenses.
Both Autobuses Rayon operating out of Phoenix and River City Shuttle out of Lake Havasu were shut down as part of "Operation Quick Strike."
Federal Regulators also temporarily suspended operations for more than 300 other companies nationwide.
Managers at Arizona Corporate Coach in Phoenix tell ABC15 they welcome the stricter inspections.
"Bring it on! We do what we need to do to keep our buses safe for all of our passengers. If we don't, we get shut down and nobody wants that," said Whitney Wilson, operations manager with Arizona Corporate Coach.
While Wilson's company stays in compliance with federal regulations, they're not surprised so many companies were suspended or shut down.
"It's not that hard to start your own company. The hardest part is maintaining your vehicles and making sure you're within compliance," said Wilson.
The company alternates pulling its buses off the roadways every 45 days for a full inspection both inside and out.
"This bus could run 10-12 thousand miles in 45 days and it needs to be done to keep the vehicle safe," explains Andrew Four with Arizona Corporate Coach Mechanic.
Four takes his job seriously and explains if something goes wrong on the roadway, it's his paperwork and inspections which will be scrutinized. Any violations carry heavy fines.
But his responsibility goes further than that.
"I look at it this way; there are 56 passengers on this bus whose lives are in my hands. If we have a problem with the bus, I'm not afraid to shut it down," insists Four.
Companies that were shut down or suspended as part of the nationwide crackdown will be allowed to open if they can show they've taken corrective action.
